| description | PROBLEM TO BE SOLVED: To provide an LED lamp unit restraining temperature rise of an LED light source by making the unit using an LED as a light source into a structure with a high heat-dissipating property, and therefore, capable of securing a given irradiation light volume through suppression of degradation of emission efficiency of the LED. SOLUTION: An LED mounting substrate 7 loaded on a heat sink 3 is housed in a space 9 formed by the heat sink 3, a reflector 2, a lens holder 4, and a projection lens 5. The heat sink 3 is structured of a plate-like base part 3a, and a plurality of plate-like fin parts 3b put in parallel from the base part 3, and a tip part 3bb of each fin part 3b at a side opposed to the base part 3a is slanted upward toward a direction contrary to an irradiation direction on an irradiation axis X of the lamp unit 1.
